Nvidia Said I Can't GAME on This GPU

This is not a review of the PSU, but it shows how well the ST1500 runs a system equipped with a pair of R9 295X2 cards.

Q & A

How to properly connect PCIe cables to high power consumption graphics cards?

According to the power supply connector overuse definition from SilverStone warranty information. A single PCIe 8pin cable and connector’s maximum current rating is 12.5A, which is 150W (+12V x 12.5A). So SilverStone’s warranty will not cover damages or malfunction resulting from the use of a graphics card or expansion card with a single PCIe 8pin connector that exceeds standard 225W total power draw (150W from PCIe 8pin connector + 75W from PCIe motherboard slot). Similarly, a graphics card or expansion card with dual PCIe 8pin connectors that exceed 375W total power draw (300W from two PCIe 8pin connectors + 75W from PCIe motherboard slot) will also not be covered under warranty.

Thus, to power high consumption graphics cards (above 225W) with two or three PCIe slots, SilverStone recommends using two or three separate PCIe cables to connect such cards to the power supply.

How to Jump Start your power supply (spare motherboard test)

Please refer to the following PDF.

How to Jump Start your power supply (Paper clip test)

Please refer to the following PDF.

ST1500 will turn on without any problems on a cold boot, but during warm boots (powering the system on again shortly after turning it off), it will trip the circuit breaker.

The power supply has a thermistor inside designed to limit inrush current. After the power supply starts up successfully, the thermistor will automatically lower its resistance to improve working efficiency. The amount of resistance is closely related to internal power supply temperature so once the power supply heats up, the resistance will decrease dramatically.

When the power supply is turned off, the thermistor will still detect high temperature and therefore provide less resistance to inrush current compared to cold boot. Since ST1500 has very higher capacity, its inrush current difference between cold and hot boot is much greater than most power supplies.

The only solution to this limitation is to consult a local electrician and install a new breaker with higher and suitable inrush current tolerance for the ST1500.

My computer will trip the circuit breaker in my house, how do I prevent this?

If your computer is tripping the circuit breaker that means it is drawing too much power from one outlet. Please do the following：

Please make sure the computer is plugged directly into the wall outlet and do not use extension socket or other multiple outlet extension cords with the computer.
If the use of extension socket is necessary, avoid combined usage with other higher powered household appliances such as TV, audio amplifier, etc…
Contact your local electrician for information on how you can upgrade your house to accommodate higher electrical draw.
